It is a basic common sense that poisonous mushrooms are good to look at, but not to eat. However, some people have insufficient knowledge about poisonous mushrooms, and cases of accidental ingestion occur from time to time. Poisonous mushrooms contain plant-based alkaloids, which are more strongly toxic. Once accidentally consumed, they can damage the liver, kidney, heart and nervous system, and even if a trace amount is absorbed into the body, symptoms of poisoning can easily appear, such as: violent vomiting, diarrhea with abdominal pain. The symptoms include: violent vomiting, diarrhea with abdominal pain, spasms, drooling, sudden laughter, excitement, trembling fingers, and hallucinations in some cases. It can be seen how serious the consequences of accidentally consuming poisonous mushrooms are. 1. Immediately call the emergency number to call an ambulance to the scene, and keep samples of poisonous mushrooms for reference of professional treatment. 2. While waiting for the ambulance, to prevent dehydration from repeated vomiting, it is best to let the patient drink “sugar brine” with a small amount of table salt and edible sugar to replenish the loss of body fluids and prevent the occurrence of shock. 3.Evacuation, gastric lavage and diarrhea. To reduce the absorption of toxin, let the poisoned person drink a lot of warm boiled water or dilute saline, and then put the finger into the throat to induce vomiting, which can be repeated several times. 4. Do not forcibly pour water into the mouth of patients who have become comatose to prevent suffocation. 5. Cover the patient with a blanket to keep warm. After the above series of treatment, it is possible to minimize the damage of poisonous mushroom poisoning to the body. In order to prevent the problem of accidental poisoning by poisonous mushrooms from occurring again, it is necessary to have a full understanding of poisonous mushrooms. Generally poisonous mushrooms can be distinguished by their appearance, slime, and smell. Poisonous mushrooms are usually more colorful in appearance, but some of the less colorful and unattractive looking wild mushrooms, such as the small fleshy brown scaly umbrella and the poisonous umbrella such as the autumn helmet spore umbrella, are equally poisonous. The poisonous mushroom cap is raised in the center, and the umbrella often has miscellaneous color spots, with filaments or small pieces of residue or scales on the surface, which usually have a pungent, sour and foul taste. Some poisonous mushrooms may secrete a sticky liquid after being torn off, which is russet and easily discolored in the air after being torn off. In fact, it boils down to one point, that is, it is better not to eat mushrooms of unknown origin, especially wild mushrooms that you do not know, so that you can avoid accidentally eating poisonous mushrooms.
